Possible Bearish Signals With Rambus Insiders Disposing Stock

Simply Wall St

Over the past year, many Rambus Inc. (NASDAQ:RMBS) insiders sold a significant stake in the company which may have piqued investors' interest. When evaluating insider transactions, knowing whether insiders are buying is usually more beneficial than knowing whether they are selling, as the latter can be open to many interpretations. However, when multiple insiders sell stock over a specific duration, shareholders should take notice as that could possibly be a red flag.

While insider transactions are not the most important thing when it comes to long-term investing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

Rambus Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the EVP & COO, Xianzhi Fan, for US$3.6m worth of shares, at about US$68.02 per share. So it's clear an insider wanted to take some cash off the table, even below the current price of US$73.28. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. Please do note, however, that sellers may have a variety of reasons for selling, so we don't know for sure what they think of the stock price. This single sale was just 36% of Xianzhi Fan's stake.
